SUSE SLES12 Security Update : kernel (SUSE-SU-2017:2779-1) (BlueBorne)

High Nessus Plugin ID 104019

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for the Linux Kernel 3.12.67-60_64_21 fixes one issue. The following security bugs were fixed :

- CVE-2017-15274: security/keys/keyctl.c in the Linux kernel did not consider the case of a NULL payload in conjunction with a nonzero length value, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call (bsc#1045327).

- CVE-2017-1000251: The native Bluetooth stack in the Linux Kernel (BlueZ) was vulnerable to a stack overflow vulnerability in the processing of L2CAP configuration responses resulting in Remote code execution in kernel space (bsc#1057950).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
